PERFECT GROUND = GREAT COFFEE
Never underestimate the importance of grinding.
The best coffee machine and the best coffee beans in the world won't do you any good if you don't understand extraction. It's time you understood coffee extraction, because only then can you avoid under-extraction and over-extraction. Both are bad for your coffee and bad for you. Avoiding this is the reason why we use different grinds for different coffee machines.
The aim when choosing the grind is to extract the perfect amount of flavour from your coffee. Too little and you have extracted too little, too much and you have extracted too much.
- too coarse = under-extraction.
this means that you have not extracted enough flavour from your ground coffee. - too fine = over-extraction.
in this case, you have extracted too much flavour from your coffee - and it becomes overpowering and unpleasant.
